So, you never really know how its going to turn out.
Course materials? I devoured Michael Waite's Quick C Prpgramming book (the one with the pink and yellow cover) in a day, and then the next day I read it all again. Did the same with Stan Lippmann's C++ book the following year, and carried the at&t cfront manual around in my backpack for ages.
I've been working pretty much exclusively in .net for the last twenty years, but C remains my favourite language - even if I almost never write any code in it nowadays.
